Corn on the cob doesn’t need a grill to be good. I figured this out during a summer when my building’s courtyard grill was perpetually broken, and I started throwing corn under the broiler out of mild desperation. Turns out, a toaster oven with a broil setting does something genuinely great to corn — the dry, intense heat caramelizes the natural sugars fast, and you get charred spots that taste smoky even though there’s no smoke involved.
The miso butter is what makes this recipe worth writing about. White miso is sweet and funky in the best way, and when you combine it with butter, a little honey, and soy sauce, you get this glossy, deeply savory glaze that clings to every kernel. It’s the kind of thing you’ll want to put on other vegetables too — fair warning. I’ve been known to make a double batch just to have extra in the fridge.
The whole thing takes under 25 minutes, start to finish. Four ears fit comfortably in most full-size toaster ovens; if yours is on the compact side, snap the cobs in half. Using a toaster oven baking sheet lined with foil makes cleanup almost painless, since that caramelized miso butter has a way of dripping.
This works as a side dish for pretty much anything — a weeknight dinner, a cookout where the actual grill is already full, or honestly just as a snack on its own. It’s not fussy. It’s just really good corn.

Instructions
-
Set your toaster oven to broil and let it preheat for at least 5 minutes. If yours runs cool, give it a full 8. You really want it blasting hot before the corn goes in.
-
While it heats up, make the miso butter. Mash together the softened butter, miso paste, honey, soy sauce, grated garlic, and red pepper flakes in a small bowl until smooth. Taste it. It should be salty, a little sweet, deeply savory. Adjust if needed.
-
Rub each ear of corn lightly with the oil. This helps the kernels get a little color before you add the butter — skip it and the corn steams instead of chars.
-
Place the corn directly on your toaster oven rack or on a foil-lined toaster oven baking sheet. Broil for 8 minutes, turning once halfway through, until some kernels are golden and a few spots are starting to look properly charred.
-
Pull the corn out and immediately brush it generously with the miso butter. Use about half of it. Put it back under the broiler for another 4 to 6 minutes, turning once, until the butter caramelizes and you get those deep amber spots. Watch it — broilers don't mess around.
-
Transfer to a plate. Brush on the remaining miso butter while everything's still hot. Scatter the chives, sesame seeds, and a pinch of flaky salt over the top. Serve right away.
Notes
If your corn ears are too long to fit in your toaster oven, just snap them in half — no shame in it, works perfectly. White miso is key here; red miso is way too strong and will overpower everything. Leftover miso butter keeps in the fridge for up to a week and is excellent on toast, roasted vegetables, or noodles. Don't skip the final butter application after broiling — that's where most of the flavor ends up.
